How Do You Make a Clock Silent?

I've tried tinkering, but it never seems to work. Is there a way to make an analog clock silent (or at least quieter), without actually turning it off (the idiot's answer to everything)? I recently had to retire my old bedside clock, and so I bought a cheap-o one at Wal-Mart for about 5 dollars...and it is the loudest thing I've ever heard. Will someone please enlighten me?

Measuring audio

I have a project where I need to be able to measure 3 or 4 microphones and decide which one is getting in the loudest input volume. In other words to know who is talking around a four persons table. Does anyone have any idea how to solve this problem? I'm using arduino (http://www.arduino.cc/) for the rest of the project so I'm able to use the arduino to measure dc voltage but how do I transfer the sound wave into a measurable dc voltage? thx in advance / david

VU LED Rhodes Piano Project

Hello all, I have a Rhodes Stage Piano (see pic), a classic 1973 workhorse. Like a guitar, the output is driven by pick-ups, and is not amplified. I would like to attach an LED VU display like you'd find on a home stereo or casstte deck. The output is controled by a potentiometer. What I'd like to do is embed LED's in plexiglass, or some other material, and have them stretch across the back of the Rhodes. (See very crude example I dummied up). The idea is that the LED's respond to the output of the piano, the loudest triggering the red LED's, which can be absoutely meaningless in real-world terms, just a visual. They also don't have to be those exact colors, but it would be nice. Can I use the LED Kit, cut the leads, add more lights and run little wires to the rear, or should I start over? I have loads of 12 volt DC transformers I can use. I also have some analog dial (needle) VU's that would be cool to add to each end, also. The Rhodes is Mono, and I believe they sell a Mono kit, too. This is the toy store.....nothing serious, just a thought. I don't mind admitting that: 1. I'm a total noob 2. I am almost clueless when it comes to electronics, but I can use a soldering iron and follow directions. All comments and suggestions welcome. I've already admitted to being not so bright so............ Thank you, rhodesdude

What is the strangest looking insect you ever encountered?

Here around me the summer is on the way! This not only means a never ending supply of mozzies but also that after a bit of rain you have a concert every evening. If you ever saw a game of soccer you know the sound of the whistle the referee uses - it is painful at close range. Now imagine you relax in your garden and right next to your chair exactly this sound comes out of the ground! Of course if you are like me and it happend during a holiday the first time you might want to investigate. But once you move the sound stops, if it starts again and you are careful you will find a small hole in the ground that seems to be the outlet of a small speaker LOL The really hard part is to actually get the thing producing the sound, I tried many times and out of ten I usually only get two out of the ground. Was too lazy so I borrowed the pic from this website, which has a lot more info on the insect in question too. What you get out of the ground looks like a cloning experiment gone wrong. A maggot like body with legs, under-developed wings (they make the noise) and a head like something from your latest horror movie. To top it all up you also get a lobster like claw that is surprisingly powerful. Fun fact: The numph of the cicada is considered to be the loudest insect of earth, reaching up to 130 decibles at the hole! And because you might think all ugly babies will be be beautiful once grown up I just say that mum and dad would not win and beauty competition either LOL Stick insects are cool, these creatures are just out of this world! What have you encountered that is weird enough to post?

Vulcan Flies!

The last air-worthy Avro Vulcan Bomber is flying again!After seven million GBP, and countless hours of work, XH558 is again in the air, and has completed weeks of tests and trials, and her crew are anxiously waiting for the permit to fly.This is wonderful news, and genuinely emotional. Vulcan is an absolutely beautiful aircraft, and I was privileged to be present at almost her last flight near Manchester well over a decade ago.I have no idea what preceded Vulcan in the airshow, because all the time the preceding act was show, Vulcan was flying in a holding pattern over the Pennine hills. Whatever was flying in front of me, all I and many of the crowd had eyes for was this shark-like presence circling on the horizon, like a predator haunting a reef.When she came closer for her actual show, it was one of the few times I have gotten genuinely emotional over a machine. Her grace, power, lines...I'm even getting a lump in my throat as I type.It is one of the highlights of my life to have been there when the Vulcan crew, believing she was about to be pensioned off forever, broke air-show rules and flew over the crowd, at low altitude, with full afterburners on.It was the loudest sound I have ever heard, explosions included. My ears actually shut down. As she went over, I screamed and shouted with sheer joy, and I could not hear a noise I made!After she passed, as hearing slowly returned, I realised that it was still noisy - every single car alarm was sounding, triggered by the noise of Vulcan's passing. There were a lot of cars.It's been years since then, and it still stands clear in an otherwise patchy memory.I am literally bouncing at the idea that I might get to see her in the air again.UnfortunatelyBut there's a hitch. They've spent millions already, but they need more. Simple day-to-day maintenance costs, plus the rising price of fuel, mean that it will cost upwards of 50,000GBP per month to keep XH558 in the air. That's a lot.I don't normally do things like this, it's close to genuine spam, but I'm asking you all a favour. As Makers, lovers of the art of machinery, I'm asking you to contribute.Donations should be sent to VTST, Bruntingthorpe Airfield, Lutterworth, Leicestershire, LE17 5QS, United Kingdom, or by ‘phone to (44)116 247 8145, or online at http://www.vulcantothesky.com .If you don't fancy sending cash, you could buy something from their shop.Donation web pageThat's it, folks - begging over.
